COMBINED SAFETY-RAZOR AND BAZOIl-BLADE SHARPENER. I

. Application filed March 29. 1915.

Another object is to provide an efiicient and improved safety razor havin combined therewith simple, inexpensive, e icient, and improved means for sharpening the razorblade thereof.

Other objects and advantages will herein after appear.

In the accompanying drawings, Figure 1 shows a general end view of the safety razor.

- Fig. 2 is a side elevation of the razor shown in Fig. 1. Fig. 3 is a plan view ofthe razor snowing its razor-blade and guard turned around about their axes. Fig. 4 is a. view similar to Fig. 3, but showing'the guard removed from the razor blade. Fig. 5 is an end elevation showin the razor coverted into a stropping machine for its blade. Fig. 6 is fragmentary sectional elevation similar to-Fig. 5. Fig. 7 is an end elevation of the strap guide. Fig. '8 is a side elevation of the strap guide.

Upon a. handle 1 is fixed a frame 2 comprising a cross-bar to the center of which said handle is secured, and posts 4, 5 located at the ends of the cross-bar. At the upper eiitremities of the posts 4, 5 is rotatably mounted a shaft (3 perpendicularly to the ban- -d,le 1 by means of its journals '7, 7 fitting Specification of Letters Patent.

screw 14 passing through a centrally located Patented Feb. 8, 1916.

Serial No. 17,718. A

opening 15 in the blade and threading into the shaft, the blade and shaft may be swung or completely rotated around their joint axes. An independent guard 16 for the razor-blade 11 provided with a centrally located opening 17. adaptable to fit the shank of screw 11, and at the extremities of said guard are formed notches 18 the sides 19, 20 of which are adapted to bear against the shaft projection 10, whereby said guard may be placed upon and alined in proper relation with the blade ll and by tightening of the screw 14 against the guard it may be firmly secured to said blade and turned around therewith about the axis of shaft 6. Preferably, the opening 17 in guard 16 is made to extend slightly in elongated form toward one side of the guard \vhereat it joins with a circular opening 21 having a diameter adaptable to pass over the head of screw 11, and the notches 18 likewise extend toward the same side of the blade. By means of this construction the guard 16 may be removed from the razor blade 11 and entirely from the machine by unthreading the screw 14 but partially and shifting the guard to aline the opening 21 with the screw and then lifting the guard off, and in a reverse manner the guard may be replaced upon the blade and secured in position, whereby the ready removal and replacement of the guard for cleaning the machineiind for purposes to. be hereinafter noted-is fiicilitated. The journal 7 of shaft 6 is threaded and projectsbeyond the post 5, and a knurled thumb-nut 23'threadiiig over said projecting journalis adapted to tighten against the post 5 to thereby lock the shaft 6 with the razor blade '11 and guard 16 against rotation, in whichever position said blade and guard may chance to be in'. Thus as shown in Fig. 3 the blade 11 with its guard 16 are locked in a situation exactl opposite to their normal position, Fig. to bring the guard 16 on top for facilitating its removal or replacement, and upon slightly unthreading the nut 23 and swinging the blade and guard half of a revolution they are restored to the normal or shaving position shown in Fig. 1 perpendicularly to the handle 1, in which position "the nut/23 may be tightened and the blade and'guard securely locked against rotation. It will be evident that, in a like manner, the blade 11 I and guard 16'may be adjusted to be disposed and locked at any angularposition, as indicated by the dash and dot lines, Fig. 1,

and such setting of theblade with its guard at an angle to the shaving handle 1 will be frequently found very convenient for shavlng.

-lVhen it is necessary to sharpen the edges of razor-blade 11, the nut 23 may ,be partially unthreaded, the guard 16 removed, and the sore. 14, tightened against the blade to firmly secure it directly to the shaft 6, with which it is'now 'free to rotate or swing about their joint axes. The shaft journal 7 projects beyond the" post 4 and carries a crank 24 which is disposed parallelly to the blade 11 and is provided at its extremity with a pin 25. Directly below the shaft 6 and parallelly thereto is mounted agroller 26 by means of journals 27,27. thereof fitting in bearings 27in the posts 4, 5, and

, said journals project slightly'beyond said Iss 34" in supports 32. Ihe eperatorthen'passcs I posts. The journal 27 carries a crank 29 having at its end 'a slot 30 adaptable to receive it he cranlepin'25. After the razorblade 11 has been rendered free to swing, the next step in the operation is to insert the cranlcpin 25 into the slot 30 ofcrank 29 as shown in Fig.- 5. A strap-guide ,31 is pro vided, Fig. 8-, comprising apair of parallel supports 32 held together by, means of a pair of parallel guiding rods 33 riveted in "cars 34- formed at the extremities of the sup Said strap-guide is adaptable to be.

ports. mounted upon the frame 2 of i the safety razor in the manner shown in Figs. 5, (3', and the operator may n'ow guide it into this po- 's ition by means of the projecting journals 7, 27 and i, 27 being passed through tlie slots a strap 35 around the roller 26 and places the ring shaped extremity 36 of the handle 1 over a. hook 37 rigidly secured to a fixed object 38, whereupon the safety razor as shown in Fig. 1 is now converted into a sha'rpening'machine as shown in Fig. fi for' its razor-blade 1-1 and is thus rendered ready for stropping or sharpening the razor-blade bears against the strap and undergoes sharpening. And as the strap extremity 41 is pulled an exactly opposite operation takes .place and the roller 26 and cranks 9.9, 30

first cause'the blade 11 to be disposed to an opposite position, shown in Fig. 6, so thatas the strap extremity 41 recedes from the mai chine the remaining diagonally opposite sides of the razor edges 39 bear against the strap and undergo sharpening. In this manner the alternate pulling of the strap extremities 41, 41' oscillates the razor-blade 11 about its axis and causes the diagonally opposite sides of its edges 39 to alternately bear against the moving strap surface until the razor edges 39 become thoroughly sharp ened. During the stropping operation the strap portions adjacent the blade 11 are maintained parallel to each other by being passed outside of, the guiding-rods 33, V Fig. 6, or inside of said rods as indicated by the dash and dot lines, Fig. 7, depending'upon the difl'erent tendencies of operators in pullmg of the strap-extremities. After sharpening of the razor-blade has been completed,

the safety razor may be readily restored to its normal'or shaving condition by unhooking the handle-extremity 36, removing the strap 35 and strap-guide 31, and disconnectmg the cranks 24,29. The uard 1 6 may be then replaced upon the bla e 11 and swung therewith to the proper position for shaving and then looked in-place by tightening the ad ustment nut 23. A sp'ring'detent 12 on roller 26 bears against a'burr 43 on'post5 to insure maintaining of said roller with the crank 29 out of the way during shaving, in

the position shown in Fig. 1.

Variations may be resortedto Within the scope of the invention, and. portions of the improvements may be used without others.
